--v-sow--n IMPROVEMENT IN ROTARY STEAM-ENGINES.

The Schedule referred to in these Letters Patent and making part of the sama.

To all whom it may concern:

Be it known that I, ELIsHA MATTEsoN, of Brooklyn, in .the county of Kings, and in the State of New York, have invented certain new and useful Improvements in Rotary Engines; and do hereby declare that the following is a full,'clear, and exact desciiption thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construction and arrangement of a rotary engine, which will be hereinafter fully set forth.

. In order to enable others skilled in the art tol which my invention appertains, to make and use the same, I

' cog-wheel, B, and the shaft' is,- outside of the frame,

connected inany suitable manner with the machinery desired to be driven.

The main cog-wheel B gears on one sidewith another cogwheel C, the journals of 'which also have their bearings in the sides ,of the frame.

Over the joint between the two wheels B and C, is

placed a steam-tight packing-box, D, which is connected, by means of a pipe, E, with ast'eam-boiler.

The steam now passing from the boiler through the pipe E into the stufiing-box, will strike the cogs of the two wheels B and C, turning them, and at the same time turning the machinery connected with the main shaft a.

The steam then passes outbelow the Wheels into a condenser, which I contemplate placingunder the frame A, and is there used. to the best advantage.

On the opposite side of the main wheel B, l place f a similar cog-wheel, C', stuiHng-box, D', and pipe, E', also connecting with the steam-boiler.

By turning o" the steam from the pipe E, and allowing it to pass through i", it will be seen that the motion of the main wheel B and shaft a is reversed, conse quently also the machinery connected therewith.

This device may be used in connection With any kind of machinery, but is especially valuable for steamboats,

as it takes up very little room, is easily managed, and

being very simple, and not as complicated as those now in use.

In case .of longvoyages, the Wheel C' may be placed In testimony that I claim the foregoing, I have hereunto set my hand, this 28th day of November, 1868.
